---------------------------+----------------------------
Implement ``inject_shorthands`` that would inject into the global name
space shorthands for the most usual units::
{{{
sage: units.inject_shorthands()
sage: 3 * kg * m / s^2
3*kilogram*meter/second^2
}}}
This can be implemented easily as in e.g.
``sage.combinat.sf.sf.SymmetricFunctions.inject_shorthands``, together
with a dictionary mapping shorthands to the corresponding units.
The main difficulty is to agree on a list of shorthands :-)
Let's start a list: s, mm, cm, m, km, g, kg, ...;
Maybe l, W, J, ...;
Maybe long names for the less usual units: ton, watt, ...
Or have something like:
{{{
sage: sage.units.mass.inject_shorthands(all=True)
}}}
that injects all the units with their long names.
